Add tlx indexer

[Tburm]

Adding indexer for the TLX contracts.

** NOTE: ** I had to add as a separate indexer and database here, since there is a limit to how many contracts can be indexed at once. The limitation is an internal postgres issue, where it runs out of memory or uses too many locks while setting up the indexes during the migration.

@marcus-snx I'm not sure if we actually need to fix anything here, but the linting is failing because I edited a sql file in the postgres service, which fails because it can't find the .sqlfluff file with the dialect configured.

I think we can fix the linting command by using the --include flag to only scan the models in the transformer service. I'll have a look at how to set that up.
